Not in this house, they don’t. I can’t be arsed to buy any product advertised on the box which has been dubbed into English. I use a supermarket own brand which is cheaper and probably made by Calgon anyway. Or rather I used to.

The water in East Anglia is notoriously hard. Ever since we moved to the back of beyond I’ve been suffering from slight contact dermatitis, and the mineral-rich water hereabouts was the possible cause. I say slight because it comes and goes and is more of a minor itchy irritant than a major malady. It’s the only downside to village life.

So we got ourselves a water softening wonder box. It sits comfortably next to the boiler and now delivers the silkiest of waters, so no more clogged pipes, furry kettles or lumpy limescale on tiles, taps and toilets. Bath time is now big bubble time. But has it cured my itch? Err, no. Maybe it’s the gardening.
